Appendix 1- Common Mechanical Failures and Maintenance
Methods of Apparatus
When the apparatus conducts recoiling test, if the display number does not change or the
rebound value has deviation, this condition is usually caused by mechanical failure. The
solutions for common mechanical failures of rebound apparatus are listed in the following
table:
No. Failure Condition Cause Analysis Maintenance Methods
I
During rebound
apparatus test, pointer
block 22 stops at the
initial place without
moving. 1. Compared with pointer piece 20
of pointer block 22, the field angle
of guide rod 26 is too small. Remove pointer block 22, and
enlarge the field angle of
pointer piece 20 appropriately
2. Pointer piece 20 is broken. Remove pointer block 22 and
change pointer piece 20
II
Pointer block 22 is
brought up before
recoiling, and can not
indicate the rebound
value normally.
1. The field angle of pointer piece
20 on pointer block 22 is too big. Remove pointer block 22 and
wrench the field angle of
pointer piece 20 smaller
appropriately
2. Tightness between pointer block
22 and guide rod 26 is too loose. Remove pointer block 22,
adjust the friction between
pointer block 22 and guide rod
26 (0.65±0.15n)
III
During recoiling
process, pointer block
22 shakes, moves up to
a certain place and
stops there. pointer block 22 rubs or bumps
spring back hammer body 7 File the upper surface or two
shoulders of pointer block 22
appropriately with a mall file
IV
Recoiling hammer mass
10 launches too early.
1. The end of paw 3 becomes small
obtuse angle. File the end of paw 3 to right
angle with a file;
2. Part of the end of recoiling
hammer mass 10 is broken. Turn the recoiling hammer
mass 10 to a certain angle or
change it.
V
Rebound apparatus can
not rebound and
recoiling hammer mass
10 can not move up.
1. The paw spring 28 of paw 3 falls
off and does not work; Install paw spring 28, or adjust
its elastic force and operating
position well.
2. The end of paw 3 is broken.
Change paw 3
；
3. The end of paw 3 wears from an
accurate angle to a big obtuse
angle. File the paw end of paw 3 to
right angle.
VI
Recoiling hammer mass
10 is reluctant to launch
or can not launch.
1. The bulge part of the end of
paw 3 touches the surface of
recoiling hammer mass 10 File the bulge part of the end
of paw 3 about 1mm upwards;
2. The end of paw 3 is acute angle File the end of paw 3 to right
angle.
VII
Impact plunger 14 can
not be extended, can
not be used.
Push button 6 is loose, the small
spring inside does not work. Hold and press the tail hood
and twist it 30 times, to make
guiding flange move
downwards, and adjust the
button spring well and screw
up push button 6.
